NAME
       gnutls_dtls_set_data_mtu - API function

SYNOPSIS
       #include <gnutls/dtls.h>

       int gnutls_dtls_set_data_mtu(gnutls_session_t session, unsigned int
       mtu);

ARGUMENTS
       gnutls_session_t session
                   is a gnutls_session_t type.

       unsigned int mtu
                   The maximum unencrypted transfer unit of the session

DESCRIPTION
       This function will set the maximum size of the *unencrypted* records
       which will be sent over a DTLS session. It is equivalent to calculating
       the DTLS packet overhead with the current encryption parameters, and
       calling gnutls_dtls_set_mtu() with that value. In particular, this
       means that you may need to call this function again after any
       negotiation or renegotiation, in order to ensure that the MTU is still
       sufficient to account for the new protocol overhead.

       In most cases you only need to call gnutls_dtls_set_mtu() with the
       maximum MTU of your transport layer.

RETURNS
       GNUTLS_E_SUCCESS (0) on success, or a negative error code.

SINCE
       3.1
